Answer: C
Step-by-step explanation: simply apply the distributive property to each half of the expression to be left with terms that can be combined.
(8x + 16y)/2 = 4x + 8y
4(x - y) = 4x - 4y
(4x + 8y) + (4x - 4y) = 4x + 4x + 8y - 4y
= 8x + 4y => C
Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level
No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05.
The correlation coefficient differs from zero when the p-value is less than 0.05.
